Sensor networks are composed of a great number of sensor nodes. Sensor nodes are typically energy restricted and hard to recharge, so reducing energy consumption has recently been a hot focus on wireless sensor network researches. One common approach is to make use of a logical structure, such as a grid, to construct an efficient routing topology for shorten the routing paths. This paper proposed...
Because of the dominating many-to-one communication pattern, traffic load is not evenly distributed over the nodes in a wireless sensor network (WSN). In a large-scale WSN, the multi-hop routing even deteriorates this traffic load imbalance by accumulating traffic flows along their paths to the sink. Understanding the traffic load distribution can guide the network-wide energy allocation, direct the...
In this paper, we propose a method to save energy consumption for the rejoin procedure of ZigBee networks. By skipping the active scan process, a rejoining node and its neighbors are able to save a large amount of energy. In addition, the rejoining node chooses the suitable potential parent by reserving and utilizing original neighbor table. This method is capable of reducing the number of rejoin...
